Serial No. 625,403.

To all whom a may concern:

Be it known that I, ANDREW MGNAUGII- won a citizen of the United States,residing at \lfilliamsport, in the county of Lycoming and State ofPennsylvania, have mvented certain new and useful Im )rovements inChocks, of which the following is a specification.

My invention relates to improvements in checks and has particularreference to a check adapted for use in packing freight to prevent theslipping thereof.

The leading object of my invention is the provision of a chock adaptedfor use in packing boxes, barrels or other heterogeneous forms offreight into metal or other cars,

vessels or vehicles to prevent the slipping thereof.

A further object of the invention is the provision of a device of thischaracter which will dispense with the use of props in cars or vesselson land or water or will serve to supplement the same and which willserve to secure the freight and prevent the slipping thereof when it ispacked in metal or other cars or vessels where it is impossible to naildown cleats or like devices to assist in securing the contents of thecars, vessels or vehicles.

To attain the desired objects of my invention, I have provided aplatform or plate upon which the freight isto be packed, said plateshaving teeth orbarbs struck there-- from, certain of the barbs beingadapted to grip the floor of the car while the others extend upward andcatch hold of the freight, the invention further residing. in the novelfeatures of construction and combination and arrangement of parts forservice substantially as described andas illustrated in theaccrmipanying drawings.

Figure 1 represents a perspective view of the device in use. Fig. 2represents a perspectiveview of the chock, and Fig. 3 repre sents aperspective view of a modified form of my chock.

. In the drawings, the numeral 1 designates the floor of a freightcar,while resting upon the" said floor are the prongs or barbs 2 of theplate 3, said plate 3 having resting thereon the box 4 having its underside engaged by the upwardly extending lip or lug 5, likewise struckfrom the plate 3.

In Fig. 3 I have shown a slightly modified form of my invention, whichis of rectangular shape, and comprises a plate 6, having,

dependlng barbs 7 at the corners, also the series of barbs 8, and thelip or lug 9.

From the foregoing description taken in connection with the drawings theconstruction and use of my improved device 'will be readily understoodand its advantages be fully up arent and it will be seen that I haveprovide a strong, sim 1e and durable device which can be employe anunlimited number of times, which can be quickly .and easily placed inposition and will not damage either the freight or the car, which willnot jolt loose as props and like fastenings do, and which isadapted foruse with various articles, light or heavy, and which may be readilyremoved without the use of tools. It will also be observed that I haveformed in my plates the opening 10 by the stamping up of the lip or lug5, said opening serving to receive a nail or hook to suspend the devicewhen not in use.

The hereinv described chock will obviate (in whole or in part) thenecessity of using nails, spikes, cleats or other projections in thefloor. or sides of cars, constructed either of wood or metal, or acombination of both, in the holds and on decks of vessels, floatingdocks, and wharves, or any vehicle carrying- In testimony whereof Iaffix my signature in presence of two witnesses.
